Abstract
The invention discloses a pesticide composite containing bispyribac-sodium and penoxsulam and an application thereof. The pesticide composite comprises effective components including bispyribac-sodium and penoxsulam, the weight ratio of the bispyribac-sodium to the penoxsulam is from 10:1 to 1:10, and the total weight of the bispyribac-sodium and the penoxsulam accounts for 1-40 percent of the weight of the pesticide composite. The pesticide composite is suitable for preventing and controlling annual weeds in paddy fields. The pesticide composite has a remarkable synergistic effect on control the efficiency of annual weeds in paddy fields compared with a mono-agent and has the advantages of reducing the dosage of the pesticide and the dosing cost, prolonging the service life of the pesticide and reducing the negative influence of the pesticide on the ecological environment.
Description
Technical field
The present invention relates to composition pesticide, particularly a kind of composition pesticide and application thereof that contains two careless ethers and penoxsuam is to be active ingredient with two careless ethers and penoxsuam, is used to prevent and kill off farmland weed, is particularly useful for preventing and kill off the paddy field annual weed.
Background technology
Two careless ethers, English common name bispyribac-sodium, the genus benzoic acid derivative, it absorbs by the root leaf and suppresses sour synthesizing of vinegar milk and hindered aminoacid biosynthesis side chain.Be selective herbicide, can effectively prevent and kill off barnyard grass in paddy field and other grassy weeds, double most of broad leaved weeds, some sedge weeds and the resistance barnyard grass grass controlled.
Penoxsuam, English common name penoxsulam, the sulfanilamide (SN) carbamide herbicides, be translocated herbicide, absorb, conduct to meristematic tissue by xylem and phloem through cauline leaf, young shoot and root system, suppress plant strain growth, make the growing point chlorosis, processing back 7 ~ 14d terminal bud reddens, necrosis, 2 ~ 4 all plant death.Penoxsuam is strong inhibitor of acetolactate synthetase, and medicament presents slower, needs the certain hour weeds just dead gradually.Can be used for preventing and kill off barnyard grass in paddy field and annual sedge weed, and effective to multiple broad leaved weed.
Being mixed of different pesticide species is the common methods of preventing and kill off agriculture resistance disease pest and weed.By the formulation of pesticide screening, filter out rational prescription, can effectively improve actual preventive effect, reduce dosage, reduce cost, delay the drug-fast generation of disease pest and weed, be the important means that agricultural synthesis is administered.The inventor furthers investigate the prescription screening of two careless ethers and penoxsuam, find that two careless ethers and penoxsuam are mixed, in certain mixed ratio scope weeds there are certain synergy or summation action, can prevent and kill off the paddy field annual weed effectively.After further study, finished the present invention.
Summary of the invention
The objective of the invention is to solve in the prior art develop immunity to drugs problem and promote drug effect of farmland weed, a kind of efficient, low toxicity, environmental protection are provided, help the two careless ether of the farmland weed comprehensive regulation and the composition pesticide of penoxsuam.
Another object of the present invention is to be used to prevent and kill off farmland weed, is particularly useful for preventing and kill off paddy field annual weed etc.
Technical scheme: the present invention is an active ingredient with two careless ethers and penoxsuam, the ratio of weight and number of two careless ethers and penoxsuam is 10:1～1:10, two careless ethers and the percentage by weight of penoxsuam weight summation in composition pesticide are 1%～40%, and all the other are to allow in the pesticidal preparations to use and the acceptable auxiliary element.
The present invention is prepared into known method and is fit to any one formulation that agricultural goes up use, as environment amenable formulations such as oil-suspending agent, wetting powder, water dispersible granules, effervescent tablet, aqueous suspension agents.
The auxiliary agent that the present invention uses comprises that solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, PH conditioning agent, defoamer, antifreezing agent, packing agent etc. are of value to active ingredient stablizes and bring into play drug effect in preparation known substance, all be the various compositions of using or allow use in the pesticidal preparations always, concrete composition and consumption are determined by testing according to the prescription requirement.
Product described in the invention can finished product preparation form provide, promptly each material mixes in the composition, the form that the composition of composition also can single agent provides, and directly mixes in jar or bucket before the use, is diluted to needed concentration then.Frequency of administration of the present invention and amount of application change with weather conditions and weeds situation, can reach the purpose of preventing and kill off by using suitable dosage.
The present composition is applicable to prevents and kill off farmland weed, is particularly useful for the paddy field annual weed.
Compared with prior art, the invention has the advantages that.
1, two kinds of active ingredients are mixed and have obvious synergistic effect, have improved preventive effect, have reduced the agricultural chemicals usage amount, have reduced cost and to the pollution of environment.
2, the combination of two kinds of active ingredients has enlarged herbicidal spectrum, and two kinds of active ingredient mechanism of action differences can overcome the shortcoming that single agent is easy to generate resistance simultaneously, prolongs the service life of medicament.The application of composition can delay or overcome the drug-fast generation of rice weed, helps agricultural synthesis and administers.Enlarged and prevented and kill off spectrum.
3, composition pesticide provided by the invention is to crop safety.
Embodiment
The present invention describes by following specific embodiment, but the invention is not restricted to following specific embodiment.In these embodiments, unless otherwise indicated, all percentages all are weight percentage.
Biologicall test embodiment.
Be mixed to the synergy of weeds for further understanding two careless ethers and penoxsuam, the inventor is mixed to two careless ethers and penoxsuam and has carried out formulation screening test.
Test material: chickweed [
Stellaria media(L.) Cyrillus] (field is collected seed and is preserved).The barnyard grass grass [
Echinochloa crusgalli(L.) Beaw Setaria] (field is collected seed and is preserved).
Test apparatus; Controlled illumination box; The accurate laboratory of POTTER spray tower; Electronic balance (sensibility reciprocal 0.1mg); Micropipette rifle etc.
Test method; Take by weighing 93% pair of former medicine of careless ether of certain mass earlier, the former medicine of 98% penoxsuam, the Tween 80 aqueous solution with 0.1% after adding acetone fully dissolves dilutes, and is mixed with single agent mother liquor respectively, according to the purpose that is mixed serial proportioning is set, each proportioning is provided with 5～7 concentration gradients.Kill the grass spectrum according to single agent and select representative susceptible weeds seed, it is standby to be cultured to 2 leaves, 1 stamen.After the weeds cauline leaf of selecting numbering handled, be placed in the illumination box incubated at room temperature 5 days, calculate preventive effect (fresh weight), then with method of least squares calculate suppress in dense EC
50(95% confidence limit) calculates co-toxicity coefficient (CTC) with the abundant method of Sun Yun again.
Co-toxicity coefficient (CTC) 〉=120 shows as synergistic effect; Co-toxicity coefficient (CTC)≤80 shows as antagonism; 80＜co-toxicity coefficient (CTC)＜120 shows as summation action.
